Figure l is a side elevation, partly broken,

showing an automobile equipped with theV heater constituting the preferred embodiment of my invention. v

Figure 2 is an enlarged detail section taken in the plane indicated by the line 2-2 of Figure l, and showing the relation of my novel heater to the interior of the automobile body. Figure 3 is a cross-section showing the upper and lower chambers in the heater body and one foraminous diaphragm in the lower chamber.

Figure 4 is a longitudinal vertical section of my novel heater per se.

Figure 5 is a detail horizontal section taken in the plane indicated by the line 5-5 of Figure 3.

Similar numerals designate corresponding parts in all of the views of the drawings.

As shown in Figures l and 2 my novel heater is arranged in horizontal position and longitudinally of the automobile below the fioor of the body thereof, the said floor being designated by l and being provided with openingsQ as illustrated.

The novel heater is made up of a cylindrical body 3 and conduits 4 extending upwardly from said body at points adjacent to the ends thereof and through said openinterior of the automobile body. said upright conduits 4 are dampers 5 adjustable through the medium of handle rods 6 which extend through the floor 1 as illustrated.

The heater body 3 is divided by a horizontal partition lwall 7 into a main lower chamber 8 and a main upper` chamber 9; the upper chamber 9 being provided vin its wall 10 with foraininations 10", for the entry of atmospheric air and being in full and To the attainment of the foregoing, the

ings 2 so as to discharge hot air into theV In thel free communication with the conduits 4, and -the lowerchamber 8 being provided at inten vals of its length with crosswise foraminous diaphragn'is l1 Ato provide horizontalparallel chambers as shown and the end chambers are provided with upwardly inclined top walls which form the ends of the horizontal partition 7 as clearly shown in Figure 4 of the drawings, therefore, the end cham- 65 bers are relatively larger than the intermee diate chambers. By this construction maxi` mum heat is obtained for the heater from the eXh aust gases as will be readily apparent.

At one end the chamber 8 is provided with 79 a discharge nozzle 12, and its opposite end is connected through the medium of a conduit 13 with the exhaust manifold of the internal combustion engine 14. From this it follows that the lower chamber 8 of the 75 Vheater body is adapted to serve as a muffler' in addition to utilizing the hot products of combustion to heat the atmospheric air which passes through the upper chamber 9 and up through the conduits 4 when the valves 5 are 80 open.

In the preferred embodiment of my invention, the muffler and heater is relatively arranged as shown in Figure l to the front and rear portions of an automobile body, 35

and in order to promote even heating of both portions the chamber 9 is divided into front and rear compartments by a transverse diaphragm or partition 9X, Figure 4.

It will be apparent from the foregoing that notwithstanding the simplicity and compactness of my novel device it constitutes an eiiicient muffler and heater; also, that by adjusting the dampers 5 the heat supplied to the interior of the automobile body may be nicely regulatedby an occupant of the automobile ,or entirely cut olf, as conditions demand.

I have entered into a detailed description A of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of `my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire,'however,to be understood as con- 105 fining myself to the specific construction and relative arrangement of parts inasmuch as in the future practice of the invention various changes and modifications may be made such as fall within the scope of my invention as dened in my appended claim.

Having described my invention what I claim and desire to secure by Letters-Patents, is z- An automobile exhaust heater comprising a body, a horizontal partition Wall dividing the body into a lower main chamber and an upper main chamber7 the upper main chamber having a foraminous portion'for the admission of atmospheric air and the lower main chamber having an intake for products oit combustion at its forward end and discharge for such products at its rear end and also having spaced oraminous diaphragms at intervals of its length and disposed 'transversely to provide parallel cham-- bers, the end portions of the horizontal par-- tition being upwardly inclined to enlarge the end chambers in the lower main chamber, a transverse partition in the upper main chamber, and upright conduits communicating With the upper main chamber at opposite sides of said transverse partition and being equipped with dampers and damper adjusting means.

In testimony whereof I aiiX my signa` ture.
